Advancements In Measuring And Modeling The Mechanical And Hydrological Properties Of Snow And Firn: Multi-Sensor Analysis, Integration, And Algorithm Development, Tate G. Meehan

Boise State University Theses and Dissertations

Estimating snow mechanical properties – such as elastic modulus, stiffness, and strength – is important for understanding how effectively a vehicle can travel over snow-covered terrain. Vehicle instrumentation data and observations of the snowpack are valuable for improving the estimates of winter vehicle performance. Combining in-situ and remotely-sensed snow observations, driver input, and vehicle performance sensors requires several techniques of data integration. I explored correlations between measurements spanning from millimeter to meter scales, beginning with the SnowMicroPenetrometer (SMP) and instruments applied to snow that were designed for measuring the load bearing capacity and the compressive and shear strengths of roads …

Multivariate Analysis Of The 2021 Boise Drought In The Context Of Natural Human Systems, Jesus Martinez-Osario

Boise State University Theses and Dissertations

Droughts generally refer to lack of sufficient water to supply specific needs, and has several categories including meteorological, hydrologic, agricultural and socioeconomic droughts [22]. Drought is triggered by the lack of or reduced precipitation, but other factors including low soil moisture, groundwater depletion, insufficient snowpack, reduced surface storage, increased evaporation, and contaminated surface water also contribute to various drought categories [12, 27].

Droughts impact many functional aspects of a community including agricultural production, recreation, access to clean drinking water, and the health of local ecosystems. Arid and semi-arid regions such as Idaho are specifically vulnerable to drought [12]. According to …
