Perennial rivers in the southwestern United States are rare sources of consistent water supply and biodiversity in otherwise water-stressed environments. Tamarisk, an invasive shrubby tree, has colonized vast portions of floodplains on these river systems, leading to channel inc…

The management and protection of National Wildlife Refuges (NWRs) requires local and regional inventories and assessments for the biological, physical, chemical, and hydrologic resources of each unit. Water resource Inventories and Assessments (WRIAs) are compiled by the U.S. Fi…
A fundamental principle underpinning conservation is to evaluate the condition of native vegetation relative to a reference state. Many ecological applications require vegetation condition as a spatially-explicit continuous map layer that covers broad landscape-scaled extents. T…
This study predicts the presence or absence of terrorism in Europe at a previously unexplored spatial scale. Dependent variables consisted of satellite imagery and socio-environmental data. Five machine learning models were evaluated over a binary classification problem, the pre…
The field of exoplanets is currently poised to benefit hugely from improved radial velocity (RV) precision. Extreme precision radial-velocity (EPRV) measurements, capable of detecting planetary signals on the order of 10-30 cm/s, will deliver integral planetary parameters, be se…
The structures comprising the human auditory periphery each perform unique functions to direct incoming sound, provide frequency-dependent gain, match impedance between air and liquids, and decompose the signal into its component frequencies. However, conductive and sensorineura…
Over the last few decades, new technologies in the form of observational satellites, measurement instruments, and model simulations have enabled the scientific community to make substantial strides to understand the drivers, mechanics, and impacts of climate change. This dissert…
Ocean color remote sensing repositories store critical environmental information about our planet. As the impacts of climate change intensify in coastal and inland water bodies, effective utilization of remote sensing platforms is essential for environmental monitoring and real-…
Accurate and timely precipitation estimates are critical for many hydrological applications, including monitoring and forecasting natural disasters, developing water resources management and planning strategies, as well as conducting climatological studies. Despite having high-r…
Cílem práce je porovnání a zhodnocení využití několika metod používaných pro určení složení historických materiálů, zejména těch využívajících odrazivostní spektrometrii a hyperspektrálním snímkování. Tyto metody jsou ve své podstatě neinvazivní, a proto velmi zajímavé pro dokum…
Climate change is already affecting food security in West Africa, posing a serious threat to the agriculture--which is mainly rain-dependent. Crop models can help investigate climate-crop relationships in order to better assist farmers. In this study, we implemented AquaCrop at …
Global population is increasing at an alarming rate with rapid urbanization of the earth’s land surface. Currently, more than half of the world’s population lives in urban areas and this number is projected to increase to 66% by 2050. Urban expansion in coastal zones is more com…
The primary goal of this thesis is to study Land Use Land Cover (LULC) Changes in the India and Bangladesh coastal islands from 1989 to 2011 that could be attributed to sea level rise. The study area consists of mainly islands in the coastal areas of India and Bangladesh in the …
This dissertation investigates spatial and temporal changes in land cover and plant species distributions on Cyprus in the past, present and future (1973-2070). Landsat image analysis supports inference of land cover changes following the political division of the island of Cypr…
The capital city of Bangladesh: Dhaka is regarded as the eighth largest city in the world in total population. Rapid change in land use and land cover (LULC) and unplanned urban expansion receive continuous attention from the local policy makers and international community. This…
Mineral dust and aerosols can directly and indirectly influence shortwave and longwave radiative forcing. In addition, it can cause health hazards, loss of agricultural soil, and safety hazards to aviation and motorists due to reduced visibility. Previous work utilized satellite…
Open path tunable diode-laser absorption spectroscopy (OP-TDLAS) is a promising technique that is proposed for detecting low concentrations of possible biogenic gases on Mars. This technique determines the concentration of a gas by measuring the amount of laser light absorbed by…
Due to the inappropriate planning and explosive population growth in urban areas, especially in developing countries, sustainable and disaster-safe urbanization has become the most important challenge for governments. Urbanization presents benefits in different ways but has led …
In the context of the SERVIR-Africa project, the SERVIR Arizona Team is developing streamflow forecast systems on African basins using Satellite Precipitation Products (SPP) to drive the models. These products have errors that need to be addressed before using them to drive hydr…
