(ASCE, 2022-04-04)Spatial and temporal variability of streamflow due to climate change affects hydrological processes and irrigation demands at a basin scale. This study investigated the impacts of climate change on the Kurau River in ... -
Runoff Prediction under Different Precipitation Scenarios Based on SWAT Model and Stochastic Simulation of Precipitation
(ASCE, 2022-03-15)To predict runoff under different annual precipitation and reflect the impact of annual precipitation and its inner-annual distribution on the runoff process, the soil and water assessment tool (SWAT) model is combined ... -
Characterization of Flow under Different Geometric Properties and Reynold Numbers in Y-Junction Bifurcated Fractures
(ASCE, 2022-03-09)Bifurcated fractures are the basic units of fracture networks. In this paper, a bifurcated fracture model is designed using Fluent software to characterize the fluid flow in a fracture network. The characterization of water ... -
Complex Adaptive System Approach for Studying the Impact of Externalities on the Success of Restoring Stream Functions
(ASCE, 2022-03-26)The overarching goal of stream restoration projects is to foster the adaptive capacities of stream functions while maintaining their resilience to excessive stresses. This paper introduces a methodology for evaluating the ... -
The Role of Climate in Monthly Baseflow Changes across the Continental United States
(ASCE, 2022-03-10)Baseflow is the portion of streamflow that comes from groundwater and subsurface sources. Although baseflow is essential for sustaining streams during low flow and drought periods, we have little information about how and ... -
