This document is a combined self-study textbook and reference manual. The material is presented in the general order of a PHABSIM study placed within the context of an IFIM application. The document may also be used as reading material for a lecture-based course. This manual provides documentation of the various PHABSIM programs so every option of each program is treated. This text is...

The upper Yellowstone River has been subject to multiple bank stabilization projects between Gardiner and Springdale, Montana, over the last 20 years. Additional channel modification activities are likely on the Yellowstone, and there is concern over the short- and long-term cumulative effects of channel modification activities on physical processes and dynamics of the river, associated...

Lake Sarez, which is located in the Pamir Mountains in Tajikistan, was created in 1911. A massive landslide, triggered by an earthquake, blocked the Murgab River valley, creating a natural dam, which was called Usoi. In 1999, the International Decade for Natural Disaster Reduction Secretariat led a mission to assess the risk and impacts in the Pamir Mountains of Tajikistan including this...

I am pleased to have had the opportunity to revise the first version of this set of course notes for the stream temperature models. In some ways, there have been many changes and in some ways the notes have stayed much the same. Generally, I was satisfied that the notes were both comprehensive and fairly easy to read. The exercises using SSTEMP have been upgraded to reflect advances in...

Executive Summary Cassin’s Sparrow (Aimophila cassinii) is a grassland species endemic to the southwestern U.S. and northern Mexico. Its behavior and ecology have been shaped by these arid ecosystems and the health of its populations is dependent on the availability of grasslands that contain a shrub component. Populations of many grassland birds have experienced dramatic declines due to...

Bottomland plant communities are typically dominated by the effects of floods. Floods create the surfaces on which plants become established, transport seeds and nutrients, and remove establish plants. Floods provide a moisture subsidy that allows development of bottomland forests in arid regions and produce anoxic soils, which can control bottomland plant distribution in humid regions...

We surveyed amphibians at 4 montane and 2 plains lentic sites in northern Colorado using 3 techniques: standardized call surveys, automated recording devices (frog-loggers), and intensive surveys including capture-recapture techniques. Amphibians were observed at 5 sites. Species richness varied from 0 to 4 species at each site. Richness scores, the sums of species richness among sites...

We explored the hydrologic and ecological responses of a headwater mountain catchment, Loch Vale watershed, to climate change and doubling of atmospheric CO2 scenarios using the Regional Hydro-Ecological Simulation System (RHESSys). A slight (2°C) cooling, comparable to conditions observed over the past 40 years, led to greater snowpack and slightly less runoff, evaporation...
