Modeling Reallocation of Reservoir Storage Capacity Between Flood Control and Conservation Purposes
… conservation purposes has been growing for some time. Evaluation of storage reallocations involving tradeoffs between flood control and conservation purposes in multiple-purpose, multiple-reservoir systems represents a new area for applying the Water Rights Analysis Package (WRAP) and Texas Water …

Suspended sediment and total phosphorus loadings from small agricultural watersheds in western Illinois
… treated as being representative of the mean daily concentration for load calculation purposes. This assumption, however, is not appropriate on streams where concentrations can change substantially within a day. In five small, rural watersheds in western Illinois, the collection and analysis …

Three-dimensional modelling of heat transfer from slab floors
… heat loss also was small, indicating that a daily time step is sufficient for energy analysis purposes. Design heat loss methods based on perimeter loss coefficients were shown to be unreliable because of a significant total area effect. Heat loss per unit area was found proportional to …

Description et analyse d'un modèle de respiration hétérotrophe appliqué à un sol agricole.
… of the model structure is given. It uses a daily time step and is derived from the CENTURY model. The model was found to be independent from the initial carbon pool contents and an exponential relationship was observed between the order of stabilisation of the different pools and their …

Managing Flow, Sediment And Hydropower In The Mekong River Basin
… Lao PDR and Vietnam. The model implements a daily time-step mass-balance simulation of flow and sediment to predict the spatial and temporal accumulation, depletion, and distribution of sediment in river reaches and in reservoirs under different flow and sediment management policies. This …

Application of the SWAT Model to Bacterial Loading rates in Kranji Catchment, Singapore
… to February 2007, the model was run twice on a daily time step. The first run included only nonpoint sources, while the second included 23 sewage treatment plant point sources throughout the catchment. Simulated results were compared to independent samples taken in 2009 by Nshimyimana (2010) and …

Ecosystem Consequences of Post-Fire Invasive Species in the Great Basin Desert
… soil moisture declined below 10%. DAYCENT, a daily time-step process-based ecosystem model, agreed well (R2 > 0.63, P < 0.01) with field-based measurements of NCE, ET and soil water content. While total annual ET was similar between sagebrush and post-fire Sisymbrium communities, increased …

Modeling the Impacts of Rangeland Management Practices on Flow and Sediment Using SWAT
… the estimation of flow and sediment yield on a daily time step to evaluate the water quality improvements achieved through the implementation of best management practices (BMPs) in Ash Creek. Ash Creek is a small un-gauged watershed located in western South Dakota and is a tributary to the Bad …

Operating Rules for Improving the Firm Yield of an Off-Stream Blending Reservoir System Used for Reducing Nitrate in Drinking Water and Drought Storage
… perspective using a simulation model with a daily time step. The water supply system in Pontiac, Illinois, which utilizes its OSBR to meet an internal nitrate-N concentration guideline of 8.0 mg/L through blending, is modeled as a case study. Using streamflow and nitrate-N data from May 1979 …

Modelling water budget at a basin scale using JGrass-NewAge system
… of the models in estimating the freshwater space-time availability and variability, however, depends on concurrent and explicitly modelling of all water budget components instead of a single component estimation and optimization. The whole water budget modelling at basin scale requires a combined …
