Stream habitat analysis using the instream flow incremental methodology

This document describes the Instream Flow Methodology in its entirety. This also is to serve as a comprehensive introductory textbook on IFIM for training courses as it contains the most complete and comprehensive description of IFIM in existence today. This should also serve as an official guide to IFIM in publication to counteract the misconceptions about the methodology that have pervaded the professional literature since the mid-1980's as this describes IFIM as it is envisioned by its developers. The document is aimed at the decisionmakers of management and allocation of natural resources in providing them an overview; and to those who design and implement studies to inform the decisionmakers. There should be enough background on model concepts, data requirements, calibration techniques, and quality assurance to help the technical user design and implement a cost-effective application of IFIM that will provide policy-relevant information. Some of the chapters deal with basic organization of IFIM, procedural sequence of applying IFIM starting with problem identification, study planning and implementation, and problem resolution.

Evolution and application of instream flow methodologies to small hydropower developments: an overview of the issues

ethods for evaluating instream flow needs have evolved over the last 30 years resulting in two categories which are defined as “standard-setting” and “incremental”. Standard-setting methodologies refer to those measurement and interpretative techniques designed to generate a flow value(s) which is intended to maintain the fishery at some acceptable level. Incremental methodologies on the other hand are organized and repeatable processes by which: (1) a fishery habitat/streamflow relationship and the hydrology of the stream are transformed into a baseline habitat time series; (2) proposed water management alternatives are quantified and compared with the baseline; and (3) project operating rules are negotiated. A hierarchical approach to small-hydro instream flow analysis is suggested.

The use of habitat structure preferenda for establishing flow regimes necessary for maintenance of fish habitat

The pursuit of simplicity in the complex management of instream and out-of-stream water uses very early led to the minimum , or “base,” flow concept and the myth that a consistent methodology could be used to establish the desired minimum flow. Such a single flow value has not proven to be practical. As water becomes fully appropriated to upstream use and storage, the minimum flow, if not violated, tends to become the average condition. This situation is manifest in a flat or stepped but fixed hydrograph throughout the stream reach of concern for much of the year.
