Land Use and Land Cover Change (LU/LC) is one of the notable human induced worldwide changes. Hence, understanding the stream flow responses of a watershed to this dynamic change is becoming fundamental for water resources management planning. The study was conducted with the objective to analyses the impact of Land use and Land cover changes on stream flow response of Wabe watershed, in Omo-Gibe basin. Land use and land cover maps were developed using satellite image of Landsat5 TM 1988, Landsat7 ETM+ 2001 and Landsat8 OLI/TIRS 2018 through maximum likelihood algorithm of supervised classification using ERDAS Imagine 2014 and ArcGIS software for satellite image processing and map preparation. A physical based, semi-distributed hydrological model SWAT was used to simulate LU/LC change effects on the stream flow responses of watershed. During the study period the land use and land cover has changed due to natural and anthropogenic activity. The results depicted that there was an incessant expansion of agricultural land, built-up area and forest cover, on the other hand declining of agroforestry; grassland and woodland were happened during from the 1988 to 2018 periods. Due to the occurred LU/LC changes, the mean monthly stream flow were increased by 5.97m3/s for wet season and similarly the dry season flow showed increasing by 0.96m3/s during the study periods from 1988 up to 2018. Generally the result indicated that large changes of the stream flow in the watershed. Hence result notified an urgent intervention, so as to regulate the LU/LC change and to reduce its strong impacts on the stream flow of the Wabe watershed.

A GIS-Based Framework to Identify Opportunities to Use Surface Water to Offse...ASADULISLAMSORIF
The state of Louisiana (Fig. 1) is
characterized by a humid subtropical
climate and receives about 150 cm of
rain per year.
Louisiana hosts about 40% of the
freshwater wetlands in the U.S. is a hub
for the petroleum industry and the third
leading producer of rice in the U.S. Louisiana is also a leading exporter of
aquaculture products
To prevent losing water resources and wetlands, and conserve existing wetlands
ecosystem for ecosystem and biodiversity services, good, wetlands habitats forstart
any sustainable development programs, it is necessary to detect, monitor and
inventory water resources and their surround uplands. Recently, AL-Razaza Lake
suffer from a critical situation because of the decreasing in the water level and
increase a salinity. We have propose a method to monitor and model the spatial and
multi-temporal changes of AL-Razaza Lake in the period 1992–2018. This study
includes pre-processing, processing and post-processing stages. In Addition, a
supervised classification was used to classify the satellite images. Validation result
reveals that the overall accuracies and kappa coefficients of the supervised
classifications were 88, 90.79, 95.94 and 87.67 respectively, and 82%, 86%, 93% and
79% respectively. The results showed that the percentage change was significant
during this period, such that the decreased surface area was from 1313.87 km2 in
1992 to 224.85 km2 in 201.The noticeable results show the rapidly decreasing in the
Lake area by 82.8% with area about 1089.02 km2 over the last three decades. All the
dehydration extended area of the Lake was replaced by soil.

Modeling the Effects of Land Use Change on FloodingAdam Nayak
Due to population growth, urban areas in Oregon have been expanding, leading to increases in impervious surfaces and net losses in wetlands, riparian vegetation, and forestation in the Northwest. Utilizing ArcGIS and NOAA’s C-CAP imagery, this study classifies and analyzes urban land use changes between 1996 and 2010. These findings shed light on the importance of land use management in urban settings and are being used by local watershed councils to advocate for changes within their stream basins.
Efficiency and Capability of Remote Sensing (RS) and Geographic Information ...nitinrane33
In this review paper, the potential of remote sensing (RS) and geographic information systems (GIS) for sustainable groundwater management and development is explored. Recent literature on the use of RS and GIS in groundwater resource management is analyzed, evaluating the efficiency and capability of these technologies throughout various stages of groundwater management. Challenges and limitations associated with their use are also highlighted, with potential solutions proposed to overcome them. Ultimately, the review concludes that RS and GIS are powerful tools for sustainable groundwater management and development, with significant benefits in terms of cost-effectiveness, accuracy, and time-efficiency. However, more research is needed to improve their integration in groundwater management and address current limitations. Overall, this review offers valuable insights into the potential of RS and GIS in sustainable groundwater management and development.

Delineation of potential groundwater recharge zones plays a vital role in sustainable management of groundwater resources. The present study is carried out to identify the groundwater potential recharge zones in Multan, Pakistan by using Remote Sensing (RS) & Geographical Information System (GIS) for augmenting groundwater resources. In Multan district (Punjab, Pakistan), the increasing population and expansion of land use for agriculture have severely exploited the regional ground water resources. Land Use Land Cover (LULC) change is an accelerating phenomenon on the surface of earth driven by anthropogenic activities including urban expansion, deforestation, and climatic variations. Intensive pumping has resulted in a rapid decline in the level of water table as well as its quality. Better management practices and artificial recharge are needed for the development of sustainable groundwater resources. In order to address these issues Geographic information system (GIS) and Remote sensing (RS) are the most efficient methods for the identification and detection of Land Use patterns. All of these techniques are used for mapping and identification of groundwater potential analysis. This groundwater potential information will be useful for the effective identification of appropriate locations for extraction of water. This study should be done to delineate groundwater potential recharge zones by using different thematic layers that were overlaid in ArcGIS. In the overlay analysis, the weights (for various thematic layers) are allocated based on a review of published literature or by expert opinion. The assigned weights are then normalized and modified using the analytical hierarchical process (AHP). The potential recharge map thus obtained and divided into four zones (poor, moderate, good, and very good) based on their influence to groundwater recharge.

1. Mapping Water Use—Landsat and
Water Resources in the United States
“A vision to
observe Earth
for the benefit
of all... ”
Interior Secretary
Stewart Udall, 1966
Water is one of our Nation’s most important natural resources,
a resource that has long been considered inexhaustible.
Yet changes in land use, climate, and population
demographics are placing unprecedented demands
on water supplies in the United States. As the
frequency of droughts increases and water
levels in aquifers and reservoirs decline,
people are wondering:
Is there enough water to meet all of our needs?
Landsat satellites are helping to answer
that question.
Water-Use Mapping
Using Landsat satellite data, scientists with the
U.S. Geological Survey (USGS) have helped to
refine a technique called evapotranspiration (ET)
mapping to measure how much water crops are
using across landscapes and through time. These
water-use maps are created using a computer
model that integrates Landsat and weather data.
Crucial to the process is the thermal (infrared)
band from Landsat. Using the Landsat thermal
band with its 100-meter resolution, water-use
maps can be created at a scale detailed enough
to show how much water crops are using at the
level of individual fields anywhere in the world.
The map on the left shows the amount of water
used in a single day by crops in irrigated fields in
southern Arizona.

Figure 1. This pair of seasonal evapotranspiration (ET) maps (May–September) shows crop water use in the San Joaquin Valley, California,
in 1990 (left) and in 2014 (right). Comparing the maps reveals changes in irrigation patterns during this period. Notice, for example, that water
use intensified in many places (increase in blue areas) and some irrigated lands (green in 1990) transitioned out of agricultural production
(reddish brown) by 2014.
From Daily Glimpses to Long-Term Trends
Evapotranspiration (ET) maps can show how much water crops
are using in a single day or during an entire growing season.
Drawing on the vast Landsat satellite image archive, it is also
possible to create maps that span decades to reveal long-term
trends in water use (fig. 1). The Landsat archive—invaluable
to water-use mapping and so much more—might never have
become a reality without the visionary support given to Earth
observation from space by Interior Secretary Stewart Udall
during the 1960s.
How Water-Use Maps Help
U.S. Geological Survey scientists can map water use at
different scales to address different water resource questions
and concerns. Field-scale maps, for example, are powerful tools
for estimating and managing water consumption on irrigated
croplands. Field-scale maps can help answer questions such as
the following:
• Where is water being used, how much, and by whom?
• Which types of crops are using the most, or least, water?
• Can water be used more efficiently without impacting
crop yields?
Basin-scale water-use maps assist in understanding water
balance and availability in river basins and watersheds. Basin-
scale maps are large-area maps and are useful for the following:
• Estimating water use by different sectors within a watershed.
• Resolving disputes regarding water rights and allocations.
• Evaluating aquifer depletions and quantifying net
groundwater pumping.
Planning Today for Water Demand Tomorrow
According to a recent Government Accountability Office report
(GAO, 2014), 40 of 50 state water managers expect water
shortages in their states between now and 2023. Addressing
concerns about water resources in the United States begins
with a clearer understanding of water availability and water-use
trends. Mapping water use based on Landsat satellite data has
demonstrated immense potential at local and regional scales
(Senay and others, 2016), and could become the basis for
planning, monitoring, and assessing water use across the Nation.
