Nowadays, special attention is paid to hydroelectric production\u0000because it is an efficient, reliable, and renewable source of energy,\u0000especially in developing countries like Cameroon, where hydropower potential\u0000is the main source of electricity production.

Groundwater droughts are caused by seasonal to\u0000multi-seasonal or even multi-annual episodes of meteorological drought\u0000during which the drought propagates through the river catchment into the\u0000groundwater system by mechanisms of pooling, lagging, and lengthening of the\u0000drought signals.

Amsterdam currently has a huge task of assessing and\u0000potentially upgrading its quay walls along the historic canals.

The backbone of the Amsterdam Ordnance Datum (NAP) is a network of about 400 primary subsurface markers.

This information is indispensable for the interpretation of water level measurements at the tide gauges along the Dutch coast. It may be provided by gravity measurements. Here we present a time-series analysis of more than twenty years of gravity measurements at the stations Westerbork, Epen, Zundert, and Radio Kootwijk. It reveals that only station Epen shows a statistically significant movement of -0.252±0.066 µGal yr−1, which corresponds to an uplift of 1.3±0.5 mm yr−1. For the other stations, the trends are statistically not different from zero at a significance level of 0.05. Corrections for water table variations are found to be indispensable; peak-to-peak amplitudes range from 4 µGal (Westerbork) to 28 µGal (Radio Kootwijk). Depsite some fundamental objections, corrections for instrumental offsets reduce the data scatter. First experiments with 7 years of soil moisture data acquired at station Radio Kootwijk reveal that the gravity signal of soil moisture variations has a standard deviation of 2.2 µGal, which is comparable to the noise standard deviation of measured gravity.\u0000","PeriodicalId":53381,"journal":{"name":"Proceedings of the International Association of Hydrological Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82509065","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The data used for the\u0000study consist of acquisitions from one TerraSAR-X frame covering a time span\u0000of approximately 1.7 years with spatial resolution of 0.25 by 0.60 m. We\u0000applied the Persistent Scatterer Interferometry (PSI) technique using the\u0000Stanford Method for Persistent Scatterers (StaMPS). Results reveal several\u0000areas of localized subsidence at rates ranging from −3.7 to −4.9 mm yr−1.\u0000Ground truthing and background verification of the subsiding locations\u0000confirmed the relationship of the subsidence with sinkhole presence.\u0000","PeriodicalId":53381,"journal":{"name":"Proceedings of the International Association of Hydrological Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81594241","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
