During the human activities dominated period, P1 (1953–1998), a significant decline (3–4 m) in the riverbeds of the mid-stream and the estuary was observed due to severe riverbed dredging. This intensive degradation coarsened the riverbed of mid-stream while that of the estuary became finer with cohesive sediments transported by the tide. During lesser human activities and no severe disaster period, P2 (1998–2009), the riverbeds of upstream and mid-stream were almost stable from 1998 to 2003, however, deposition was found from 2003 to 2009 as the river flow increased. Conversely, bed elevation of the estuary increased by about 0.36 m from 1998 to 2003 and erosion was initiated between 10–23 km from 2003 to 2009. During disasters dominated period, P3 (2009–2021), morphological responses differ spatially. Although disasters supplied huge sediment, they deposited in the upstream first and gradually moved to mid-stream. Currently, 1.13 Mm³ were deposited in mid-stream where the largest sediment volume was extracted during P1. Thus, sediments supplied by disasters have not reached the estuary yet. Furthermore, the bed shear stress of the estuary during P3 was high (3–20 N m^-2) due to the high river flow caused by disasters. That high river flow eroded the surface mud and bottom sand layers, resulting in the parallel decline of both layers. As a result, 1.92 Mm³ of sediments were eroded from the estuary from 2009 to 2019. These results indicate that both high river flow caused by disasters during P3 and insufficient sediment supply caused by riverbed degradation during P1 are responsible for the erosion of the estuary during P3.</div></div>","PeriodicalId":362,"journal":{"name":"Journal of Hydrology","volume":"648 ","pages":"Article 132497"},"PeriodicalIF":5.9,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143177238","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hence, we integrate multiple-source observations and multiple-model simulations to quantify lake heat storage and its impacts on lake evaporation in the ice-free period for Yamzhog Yumco, an alpine deep lake in the southern Tibetan Plateau. We first calculate lake heat storage based on a regression relationship between the modeled (<em>R_n</em> – <em>G</em>) and EC-observed (<em>H</em> + <em>LE</em>) to deal with the energy non-closure problem inherent in the EC system. Then, we quantify lake heat storage’s impacts on evaporation using multiple evaporation estimation models with lake heat storage considered or not and observations of three types of evaporators. The PE-III model can optimally estimate lake evaporation when considering lake heat storage. By contrast, the average daily evaporation is overestimated before early October while underestimating afterward with models neglecting lake heat storage, peaking 4–6 months earlier than EC observation. Besides, the observed evaporation differences between the EC technique and three types of evaporators vary with the evaporator scale related to heat storage magnitude. We also reveal that net radiation and heat storage capacity jointly control lake heat storage, whose impacts on lake evaporation are prominent when deepening lake depth.

Most previous work on the effect of urbanization on peak flows has considered urbanization alone and only the spatial variation in flood quantiles or its mean temporal effect, and most work on the effect of nonstationarity in climate has focused on single-station analyses, which give uncertain results for extreme quantiles. To address these gaps, three approaches to the statistical estimation of the joint effects of changes in impervious cover and climate on the estimation of peak-flow quantiles were compared: single-station quantile regression; a fixed effect panel-quantile regression (pQR) method using a location (mean) shift to homogenize the panel; and a location-scale panel regression model (pQRmom), which accounts for both scale (variance) and location effects. The different approaches were applied to a dataset consisting of instantaneous annual peak flows from 127 minimally nested basins in the midwestern United States with at least 4 % change in imperviousness. The annual maximum daily discharge from a water-balance model was selected as the primary climate predictor; in addition, to provide a comparison of climate predictors, precipitation was also considered. The coefficients from single-station regressions were usually sufficiently certain to determine the effects of climate variation but usually too uncertain to estimate the effects of urbanization. The panel-quantile regression approaches give much more certain results, but their estimates of quantile dependence differ: although both indicate urbanization effects decreasing with decreasing annual exceedance probability (AEP), the pQRmom urbanization coefficients are insignificantly different from zero for AEPs less than 0.10, whereas the pQR coefficients remain positive and are significant except for AEP = 0.01, the smallest AEP value considered. Although the location-scale structure of the pQRmom approach has less flexible quantile dependence than the pQR approach, the pQRmom approach has somewhat lower overall error, and it is found that by subsetting the dataset to homogenize the scale effects, the pQR and pQRmom results become similar, indicating the insignificant urbanization coefficients for small AEPs of the pQRmom results are likely correct for the study dataset.</div></div>","PeriodicalId":362,"journal":{"name":"Journal of Hydrology","volume":"648 ","pages":"Article 132281"},"PeriodicalIF":5.9,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143177237","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The observations and simulations indicated that the spatial distribution of amount effect of daily precipitation isotopes for each season is not limited to the traditional low latitudes. When the seasonality of precipitation isotopes is filtered or reduced, the areas with amount effect on a daily scale are enlarged. On a daily scale, there is a spatially coherent amount effect in summer, while in other seasons some areas without an amount effect can also be observed, especially in the northeastern part of China in winter.

After the seasonality is eliminated, as the time scale increases from daily to monthly and annual scale, the spatial patterns of amount effect are generally similar. The seasonality of spatial patterns of amount effect is associated with atmospheric circulation.
