This study utilized open-access Sentinel-2 satellite data to enhance conservation management by enabling near-real-time monitoring and assessment of hydrological dynamics in conserved lands across Nebraska, United States. Using machine learning and Google Earth Engine, this research classifies surface water cover rate for different conserved land sites in Nebraska in 2018–2021. The results of the study confirmed successful inundation performance in conserved wetland sites under Wildlife Management Areas (WMA), Wetlands Reserve Program (WRP), and Waterfowl Production Areas (WPA). The WMA sites had the highest inundated area rate of 16.41%, indicating active hydrological inundation of the core conserved land areas. The WRP and WPA sites reached a mean annual surface water cover rate of 8.07% and 7.51%, respectively, demonstrating occasional flooding or periodic inundation of core wetland areas but limited inundation coverages of the surrounding areas. The findings confirmed that wetland conservation practices are functioning very well on the sites with higher inundation rates, but hydrological restoration at the watershed scale could boost conservation performance for the entire conserved land areas.

This study investigated the water quality of the Jhapjhapia River, Khulna, Bangladesh using the Water Quality Index (WQI). For many purposes like agriculture, fish farming, and household and industrial activities, surrounding people depend on these water sources. Hence, this study examined the physico-chemical attributes and Weighted Arithmetic Water Quality Index (WAWQI) of three (03) different stations, collected during the monsoon and winter seasons. Among the investigated parameters, ten (10) crucial parameters were considered for the evaluation of water quality. Throughout the research period, the pH value ranges from 7.65 to 7.79. From Station-1 to Station-3, the concentration of EC, TDS, and DO was steadily reduced (Station-1>Station-2>Station-3). The analytical results found that the water transparency ranged from 5 to 10 cm while BOD ranged from 1.85 to 2.71 mg/l and 1.79 to 2.75 mg/l in the monsoon and winter seasons respectively. The levels of total hardness varied from 95 mg/l to 160 mg/l and 130 mg/l to 225 mg/l whereas total alkalinity ranged from 108 to 140 mg/l throughout the monsoon and winter season. Similarly, Ca 2+ value ranged from 24.71 to 28.05 mg/l and 34.74 mg/l to 42.01 mg/l and Mg 2+ ranged from 10.93 to 6.07 mg/l and from 5.93 mg/l to 8.56 mg/l correspondingly. The overall WQI value is found between 51 to 75, demonstrating the status of water quality is poor (Grade-C), unhealthy for drinking without proper treatment though can be used for irrigation and industrial purposes till now. Therefore, this study seeks appropriate strategic initiatives and conservation measures with proper monitoring to stop the deterioration of the water quality for sustaining the health and livelihood of many people who depend on it.","PeriodicalId":17234,"journal":{"name":"Journal of The American Water Resources Association","volume":"2 1","pages":""},"PeriodicalIF":2.4,"publicationDate":"2023-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88562568","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to accurately predict runoff and soil erosion in each watershed, the baseline effective hydraulic conductivity (<i>K</i>_be), interrill and rill erodibility (<i>E</i>_IR and <i>E</i>_R), and monthly precipitation standard deviations (<i>P</i>_stdev) were calibrated in WEPP using observed runoff and total suspended solids data from five Minnesota Discovery Farms field sites. Before calibration, Nash–Sutcliffe model efficiency (NSE) and percent bias (PBIAS) values for predicted versus measured monthly average total runoff (<i>R</i>_avg-T), runoff ratios (RR_T), and total soil loss were generally not in acceptable ranges. After calibration, the NSE values showed very good fits between measured and predicted monthly <i>R</i>_avg-T (0.64–0.98), RR_T (0.66–0.93), and soil loss (0.58–0.80).
