Desatoya Mountains Project and Porter Canyon Experimental Watershed FY2013Pion (Pinus spp.) and juniper (Juniperus spp.) (PJ) currently occupy approximately 19 million hectars in the Intermountain West. Prior to 1860, approximately 66% of what is now woodland occurred as sagebrush plant communities.This watershed scale project: Documents the impact of PJ treatments in formerly sagebrush steppe communities on understory vegetation composition, hydrologic function, and surface runoff and soil erosion at the landscape scale. Expands the snow monitoring component to understand snow dynamics and timing of plant phenology in cut and uncut treatments. Secures expertise to analyze existing datasets.

The HVSR technique, commonly referred to as the passive-seismic method, is used to estimate the thickness of unconsolidated sediments and the depth to bedrock (Lane and others, 2008; Fairchild and others, 2013). The passive-seismic method uses a single, broad-band three-component (two horizontal and one vertical) seismometer to record ambient seismic noise. In areas that have a strong acoustic contrast between...

The amount of information collected on water rights is extensive and increases each year. The Kansas Department of Agriculture, Division of Water Resources (KDA-DWR), currently maintains an Oracle-based RDBMS called the Water Rights Information System (WRIS). The WRIS contains over 70 relational tables that store data on points of diversion (e.g. ground-water wells and surface water intakes), place of use, authorized quantity and rate allocations, historic reported water usage, and a host of other parameters.

These worksheets contain the basic survey data (dates, instruments, reference elevations, foresights, distances from reference pins, and elevations). An additional worksheet contains the measured unit-volume (m^3/m) of chronostratigraphic units deposited during the time interval between two sequential surveys and the unit-volumes of each chronostratigraphic unit eroded during the same time interval. A final worksheet contains the age and transit-time distributions for selected surveys.
