Optimization Techniques for Instream Flow Allocations
The issue of instream flow maintenance is an aspect of environmental quality which is now required as part of the project planning process of water resources development. A mathematical programming methodology is developed which provides an analysis technique for multipurpose reservoirs for both …

Prioritizing The Upper Clark Fork River Tributaries for Instream Flow Restoration
… Steering Committee, have formed to monitor the flow of our rivers. In order to assist the Steering Committee and river advocacy groups working within the Upper Clark Fork River Basin, this paper provides a comprehensive review of the studies on existing flows and target flows in the upper river, …

RECOMMENDATIONS FOR INSTREAM FLOW RIGHTS ON NATIONAL FOREST LANDS IN MONTANA
A unique opportunity exists to create instream water rights on national forest lands in Montana as a result of the US Forest Service Reserved Water Rights Compact between the US Forest Service (USFS) and the state of Montana, which went into law in 2007. Instream water rights on national forest …

Using MODFLOW to Predict Impacts of Groundwater Pumpage to Instream Flow: Upper Kittitas County, Washington
… Based on the USGS Yakima River Basin groundwater flow model (hereafter the YRB-GFM), an Upper Kittitas County groundwater flow model (hereafter the UKC-GFM) was extrapolated to refine the Upper Kittitas County modeled region. This new model constitutes an M.S. thesis, done in collaboration with …

Habitat tools for assessing instream-flow needs for fishes in the upper Roanoke River, Virginia
… of this research was to formulate new tools for instream-flow analyses, with emphasis on protecting fish assemblages in speciose, warmer-water streams. This included habitat and fish data sets for the upper Roanoke River (URR) in southwestern Virginia, collected during the warmer, low- f low …

Evaluation and Use of Stream Temperature Prediction Models for Instream Flow and Fish Habitat Management
… dependent on model and stream, were lateral inflow, starting-water, air, and wet-bulb temperature. All three models predicted well, therefore, selecting a model to assess alternative water management scenarios was based on model capabilities. The RQUAL model, used to predict SRT temperatures …

Instream flow methodologies: an evaluation of the Tennant method for higher gradient streams in the national forest system lands in the western U.S.
… Tennant introduced a method for determining instream flow requirements for fish, known as the 'Montana method', or more commonly the Tennant method. The method uses a percentage of average annual flow (AAF) to determine fish habitat quality. From 58 cross sections from 11 streams in Montana, …

Ecohydrologic Indicators of Low-flow Habitat Availability in Eleven Virginia Rivers
… and competition for freshwater is threatening instream uses including ecosystem services and aquatic habitat. A standard method of evaluating impacts of alternative water management scenarios on instream habitat is Instream Flow Incremental Methodology (IFIM). The primary outputs of IFIM …

Defining flows to protect instream biota : a critique of the instream flow incremental methodology and the development of a hierarchical habitat-based approach, using the pennant-tailed catlet, Chiloglanis anoterus in the Marite River, South Africa
… thesis focusses on two approaches to determining Instream Flow Requirements (IFR) for regulated rivers, specifically in the sub-tropical eastern region of South Afiica using a flow-sensitive fish species, the pennant-tailed catlett 07iloglanis anoterus. In response to the diminishing and altered …

Spatial dynamic groundwater regulation to ensure adequate instream flows for salmon
… Groundwater pumping can lead to a reduction in instream flows of nearby streams in a process known as stream depletion. From an economic standpoint, policies intended to leave adequate quantities of water instream for any purpose should aim to minimize the welfare losses accrued by irrigated …

Safe Yield for Jointly Operated Reservoir System and Examination of ENSO Impacts
… accommodates the various storage and river flow dependent instream flow requirements. It is found that the water treatment plant capacity, instream flow requirements, and flows themselves limit the yield. Inflows to the reservoir are very important factor in determination of safe yield for …

The effect of depth-velocity correlations on aquatic physical habitat usability estimates
Recent developments in instream flow evaluations have resulted in a variety of assessment methodologies. Of these, the Instream Flow Incremental Methodology permitted consideration of both physical habitat parameters (e.g., depth, velocity, substrate and temperature) and preferences for certain …

Modeling Low Flow Hydraulics in Alluvial Channels (pools-Riffles, Open)
The investigation of the flow condition has become important in recent years as a means of determining critical levels of water pollution, aquatic habitat and instream flow needs. To assess these critical conditions, it is necessary to predict the hydraulic response of a river system to a given low …

Assessing effects of an overwinter dewatering on the egg-to-fry survival of brown trout in a Montana stream
Natural instream flow regimes are necessary for the ecological health of streams, including the maintenance of healthy fish populations. Economic interests such as agriculture, mining, and other industries remove water from streams, which can negatively affect fish populations. Wintertime …
