The Massachusetts Reservoir Simulation Tool The Massachusetts Reservoir Simulation Tool
The Massachusetts Reservoir Simulation Tool is a screening-level model developed to examine the effects of reservoirs on the natural streamflow of streams in Massachusetts. The Massachusetts Reservoir Simulation Tool simulates the daily water balance equation of a water supply reservoir and estimates the magnitude, frequency and duration of spillage below the dam over the period of...
CENTROID CENTROID
Tests the null hypothesis that two samples of recoveries belong to the same bivariate distribution.
SPECRICH2 SPECRICH2
Estimates the total number of species from species presence-absence data on multiple sample sites or occasions using model M(h) from program CAPTURE.
PRESENCE PRESENCE
Estimates patch occupancy rates and related parameters.
BROWNIE BROWNIE
Computes estimates of survival and recovery rates for 2-age class band-recovery data.
RDSURVIV RDSURVIV
Computes estimates of survival and capture probability using capture-recapture data with "robust-design" models and recoveries.
LOLASURVIV LOLASURVIV
Computes estimates of survival and capture probability for open capture-recapture models when sex is not allways known.
nestAbund nestAbund
An R package to estimate nest abundance using a state-space superpopulation capture-recapture approach in which inference about detection probability is based on the age at first detection, as opposed to the sequence of re-detections in standard capture-recapture models.
HyDroDSS: Hydrologic Drought Decision Support System - Software page HyDroDSS: Hydrologic Drought Decision Support System - Software page
The HyDroDSS is designed to provide water managers with risk-based information for balancing water-supply needs and aquatic-habitat protection goals to mitigate potential effects of hydrologic drought.
GENCAPH1 GENCAPH1
Generates capture-history data for given s,theta,p,c.
SELDM: Stochastic Empirical Loading and Dilution Model - Software page SELDM: Stochastic Empirical Loading and Dilution Model - Software page
Overview The Stochastic Empirical Loading and Dilution Model (SELDM) is designed to transform complex scientific data into meaningful information about the risk of adverse effects of runoff on receiving waters, the potential need for mitigation measures, and the potential effectiveness of such management measures for reducing these risks.
COMDYN COMDYN
Computes estimates of species richness using large scale data.
