    Ecosystem Health Assessment and Driving Factor Analysis of Panjin Reach of Liaohe River Basin Based on PSR Model by YANG Heqing, HU Huiqin, ZHANG Qinxu, QIN Mengen, ZHANG Mingliang, HOU Jun

    Published 2023-01-01
    “…To evaluate the ecosystem health of Panjin reach in the Liaohe River Basin,based on the data collected from 2010 to 2020 in the study area,this paper adopts a pressure-state-response (PSR) evaluation model and selects 13 evaluation indicators.The entropy weight method is introduced to calculate the weight,and the fuzzy relation matrix method is adopted to calculate the membership degree.As a result,the comprehensive evaluation index (CEI) in the Panjin section of the Liaohe River is obtained,and then the ecosystem health of the study area is evaluated.The results show that the CEI indexes of this area from 2010 to 2020 are 0.343,0.341,0.279,0.425,0.418,and 0.464 respectively,and the overall ecosystem health changes from an “unhealthy” level to a “generally healthy” level.This study indicates that the total volume of water resources,policies and regulations,construction of protected areas,landscape diversity index,industrial wastewater discharge,and chemical oxygen demand in water have a great influence on the ecosystem health of the study area,with the weight values of 0.209 7,0.179 7,0.141 9,0.136 8,and 0.106 3 respectively.The overall weight of hydrologic and water environment factors involved in all the indicators is 0.620 7,with the effect degree more than half of all indicators.These hydrologic and water environment factors play a more direct role in this area.Therefore,the ecosystem health improvement in the study region requires management and remediation from the perspective of hydrology and the water environment.Thus,to improve the ecosystem health of the study area,it is necessary to carry out the management and regulation from the perspectives of hydrology and the water environment.…”

    Streamflow and sediment simulation in the Song River basin using the SWAT model by Shams Quamar, Pradeep Kumar, Harendra Prasad Singh

    Published 2025-01-01
    “…Thirteen parameters were selected for calibration, with eight identified as highly sensitive, reflecting key hydrological processes of the area. The model was calibrated for the period 1974–1995 and validated from 1996 to 2004, with additional testing using field data collected in 2022–2023 through Acoustic Doppler Current Profiler (ADCP) measurements. …”

    Improved urban runoff prediction using high-resolution land-use, imperviousness, and stormwater infrastructure data applied to a process-based ecohydrological model. by Jonathan Halama, Robert McKane, Bradley Barnhart, Paul Pettus, Allen Brookes, Kevin Djang, Vivian Phan, Sonali Chokshi, James Graham

    Published 2023-11-01
    “…The results demonstrate that the newly improved VELMA model allows for more accurate modeling of hydrology within urban watersheds. Being a fate and transport ecohydrology model, the improved hydrologic flow enhances VELMA's current capacity for modeling nutrient, contaminant, and thermal loadings.…”

    Complexity to Forecast Flood: Problem Definition and Spatiotemporal Attention LSTM Solution by Yirui Wu, Yukai Ding, Yuelong Zhu, Jun Feng, Sifeng Wang

    Published 2020-01-01
    “…Considering the significance of modeling attention capability among hydrology factors, we believe extraction of discriminative hydrology factors not only reflect natural rules in physical space, but also optimally model iterations of factors to forecast run-off values in cyber space. …”

    Attribution Identification of Runoff Changes Based on the Budyko Elasticity Coefficient Method: A Case Study of the Middle and Upper Reaches of the Jinghe River in the Yellow River... by Xueliang Wang, Haolin Li, Weidong Huang, Lemin Wei, Junfeng Liu, Rensheng Chen

    Published 2024-12-01
    “…The Sen’s slope estimator and the Mann–Kendall test (M–K test) are implemented to examine the spatial and temporal trends of the hydrological factors, while the elasticity coefficient method based on Budyko’s theory of hydrothermal coupling is employed to quantify the degree of runoff response to the various influencing factors, from 1971 to 2020. …”
