Statistical analysis for streamflow prediction
… by basins of similar topography and climate. Streamflow prediction would be made by mathematical synthesis from the standard deviation parameter computed from the graphical relationships established for each region. The value of such a relationship was evidenced by the general consistency of …

A GIS application for regional streamflow analysis
… procedure used by hydrologists to estimate streamflow parameters for ungauged streams. The procedure involves analyzing historical flow records for streams in a particular region, in order to estimate flows for other streams in the region. Traditionally, the process of obtaining and …

Meteorological Impacts on Streamflow: Analyzing Anthropogenic Climate Change's Effect on Runoff and Streamflow Magnitudes in Virginia's Chesapeake Bay Watershed
… VADEQ's VA Hydro hydrologic model to investigate streamflow's response to climate. Temperature changes across the study area were minimized in the tenth percentile scenario (+1.02 to +1.24◦C) and maximized in the ninetieth (+2.20 to +3.02◦C), with evapotranspiration change following this trend …

Streamflow synthesis and water allocation by water right priorities
A computerized streamflow model was developed that allocates water by the doctrine of prior appropriations. The function of the model is to simulate the impacts of physical or legal changes in a stream system managed on the basis of priority of water rights. Given a specified value of streamflow …

Base Flow Recession Analysis for Streamflow and Spring Flow
… The base flow recession analysis for both streamflow and spring flow has been extensively studied in the literature. Studies have shown that the recession behaviors during the early stage and the late stage are different in many watersheds. However, research on the transition from early …

Geospatial and statistical foundations for streamflow synthesis in West Virginia
Streamflow values must be synthesized for locations where flow measurement stations, in applications such as the West Virginia SWAP program, are lacking or where only intermittent measurements are available (West Virginia Department of Health and Human Resources, 1999). This research describes an …

Understanding the causes of streamflow changes in the Eurasian Arctic
Since the 1930s, streamflow from Eurasian rivers discharging to the Arctic Ocean has been increasing. Much of this change has been attributed to increased precipitation, but recent studies show inconsistencies in long-term streamflow and precipitation trends. Alternatively, these inconsistencies …

Quantifying Uncertainty in Velocity-area Streamflow Measurements Under Non-ideal Conditions
… measurements at each vertical. Keywords: streamflow, hydrometrics, velocity-area method, flowtracker2, discharge, uncertainty, IVE, FLAURE, ISO

Assessing the Robustness of Deep Learning Streamflow Models Under Climate Change
Long Short-Term Memory networks provide the most accurate rainfall-runoff predictions to-date, but their reliability under climate change is not well understood. We explore the robustness of these models under climate nonstationarity by creating train and test data splits thatare designed to …

Determination of streamflow characteristics for ungaged Texas streams using regression analysis
… mean, 7Q2 (7-day, 2-year low-flow), and 7Q10 are streamflow characteristics used to determine stream waste load allocations. Predictive equations for these characteristics of ungaged Texas streams are developed using multiple regression analysis to relate streamflow characteristics to basin …

Understanding Streamflow Change at the Scale of a Major City: Chicago
Urban and economic development and climate change have made the non-stationarity of stream flow records an emerging phenomenon in hydrology. This thesis studies the systematic shifts in stream flow that have been observed in urban, suburban and agricultural watersheds in and around the Greater …

Streamflow Generation in alpine Catchments: The role of hydrological and geochemical information
… identifying the main mechanisms controlling streamflow generation and understanding the nature and variability of streamflow in Alpine streams, represent a very important contribution towards a better understanding of these complex systems. Among the multiplicity of streamflow sources (e.g., …

Enhanced Soil Moisture and Streamflow Estimation in Ungauged or Data-Scarce Watersheds
… generation, or pollutant export) and integrated (streamflow) watershed responses. While streamflow is commonly used to constrain model parameters due to its availability and integrative nature, the issue of equifinality, where multiple parameter sets yield similar streamflow, but divergent …

Improving ensemble streamflow forecasts through targeted post-processing and rating curve uncertainty analysis
La prévision des crues joue un rôle essentiel dans la gestion efficace des ressources en eau et l'atténuation des risques d9inondation. Malgré les avancées récentes, les systèmes de prévision d'ensemble existants sont souvent confrontés à des problèmes de fiabilité et de sous-dispersion. …
