The drainage basin
The document discusses the hydrological cycle within a drainage basin. A drainage basin is the area of land drained by a river and its tributaries, forming an open system with inputs, stores, flows, and outputs of water. It instructs the reader to label a diagram of a drainage basin with features including the source, watershed, tributaries, confluence, and mouth.
Drainage Basins VLE
A drainage basin is the area of land that drains water to a common outlet such as a river or lake. It is delimited from adjacent basins by a watershed divide. A drainage basin can be modeled as an open system with inputs like solar energy and precipitation, stores like glaciers, lakes, soil and vegetation that hold water, and outputs like evaporation and river discharge that remove water from the system. Water and energy from outside sources enter the basin and water leaves through various transfers and outputs.
Hydrograph explanation and animation
Hydrographs show changes in river discharge over time in response to rainfall. They are constructed by measuring river discharge during and after storms. A typical hydrograph has a rising limb as discharge increases, peaks at maximum discharge, then declines on the recession limb. Analysis of hydrographs can predict flooding and inform flood prevention. Characteristics like basin area, slope, soil, land use, and rainfall patterns influence a hydrograph's shape and timing.

This assignment aims to discuss two different topics. The first topic is about the difference between informed and uninformed search, its types, and real-life examples. The second topic is about the difference between strong AI and strong method. Both of these topics are significant in the field of artificial intelligence and will be discussed in detail below.
Topic 1: Difference between Informed and Uninformed Search, Types, and Real-Life Examples
In artificial intelligence, a search algorithm is a way of finding a solution to a problem. A search algorithm can be informed or uninformed. Informed search algorithms use heuristic functions to guide the search towards a goal, while uninformed search algorithms do not use any heuristic function. In this section, we will discuss the difference between informed and uninformed search, its types, and real-life examples.
1.1 Difference between Informed and Uninformed Search
The main difference between informed and uninformed search is the use of heuristic functions. Heuristics are problem-solving techniques that use a practical approach to find a solution, but not necessarily the best solution. Informed search algorithms use heuristic functions to guide the search towards a goal, while uninformed search algorithms do not use any heuristic function.
Informed search algorithms are more efficient than uninformed search algorithms because they use information about the problem to guide the search. For example, in the A* search algorithm, which is an informed search algorithm, the algorithm uses a heuristic function to estimate the cost of the solution from the current node to the goal node. This information helps the algorithm to make informed decisions about which node to expand next.
On the other hand, uninformed search algorithms do not use any heuristic function to guide the search. For example, in the depth-first search algorithm, which is an uninformed search algorithm, the algorithm starts at the root node and explores as far as possible along each branch before backtracking. This algorithm is not very efficient because it does not take into account any information about the problem.
1.2 Types of Informed and Uninformed Search Algorithms
There are several types of informed and uninformed search algorithms. In this section, we will discuss some of the most commonly used search algorithms.
1.2.1 Uninformed Sear

Module 5: Highway Drainage and Highway Economics
The document discusses highway drainage, which involves removing surface and subsurface water from roadways. Excess water can damage pavement and cause failures. The drainage system includes surface drains to remove surface water runoff, and subsurface drains to intercept groundwater. Surface drainage components are the road crown or slope, cross drains, and roadside drains. Hydrologic analysis estimates maximum runoff quantity using factors like rainfall intensity and drainage area. Hydraulic analysis then designs drains to convey this water away. The document provides examples to demonstrate designing a surface drainage system.
To be presented
This document discusses the design of highway drainage for the Thankot-Chitlang road section in Nepal. It covers the importance of drainage, requirements for highway drainage systems, and the specific design of surface and subsurface drainage features for this road project. The surface drainage design includes determining stormwater discharge amounts, dimensions for side drains and culverts using Manning's equation. The subsurface drainage design considers lowering the water table and controlling seepage and capillary moisture.
Drainage Engineering (darcy's Law)
The document provides an overview of the key concepts and principles covered in a Drainage Engineering syllabus. It discusses Darcy's law and the fundamental equations governing groundwater flow. It also addresses topics like waterlogging, salinity, drainage system design, land reclamation, canal lining, and cross drainage structures. Major drainage projects in Pakistan are also introduced. Recommended textbooks on drainage and irrigation engineering are listed.
1_Drainage_Design.ppt
This document discusses drainage systems for removing excess water from agricultural land. It describes two types of drainage: surface drainage, which involves removing water from the surface of the soil through ditches or land forming; and subsurface drainage, which uses buried drains or ditches to lower the water table. The key aspects of designing drainage systems are estimating water flows, determining appropriate drainage coefficients based on rainfall or irrigation rates, setting drain depth and spacing, and selecting drain diameters and gradients. Drainage is crucial for improving soil conditions for crop growth in both rain-fed and irrigated agricultural areas.
Hillslope poster_PAEP_finaldraft2
This document summarizes a study that measured soil moisture content at two sites in Pittsburgh over three months to understand soil water dynamics and implications for green infrastructure. Sensors measured soil moisture in different layers. Soils at one site drained slower and remained wetter than the other site. Unexpected patterns like bottom-up wetting at one site suggest complex hydrologic influences like leaky infrastructure or bedrock fractures. These findings have implications for proper placement and design of green infrastructure like infiltration trenches to ensure optimal performance.

Key considerations for drainage design include drainage coefficient, drain depth and spacing, drain diameter and gradient, and drainage filters. The Hooghoudt equation is used to calculate drain spacing based on soil properties and drainage coefficient.
Drainage Engineering (Drainage and design of drainage systems)
This document provides information on drainage and the design of drainage systems. It discusses the following key points in 3 sentences:
Land drainage and field drainage are the two main types of drainage, with field drainage focusing on removing excess water from the root zone of crops. The main goals of field drainage are to bring soil moisture below saturation to allow for optimal plant growth and to improve soil structure and hydraulic conductivity. The different methods of field drainage include horizontal drainage methods like surface drainage and sub-surface drainage, as well as vertical drainage through tube wells.
drainage-engineering-ppt.pdf
This document discusses the design of drainage systems. It defines drainage as the removal of excess water from an area. There are two types: land drainage for large areas and field drainage for agriculture. The main aims of field drainage are to lower the soil moisture level, improve soil structure, leach salts, and allow for cultivation. Drainage design considers the drainage coefficient, drain depth and spacing, drain diameter and gradient, and drainage filters. The document provides methods to calculate peak rainfall flows, drainage coefficients for different rainfall and irrigation scenarios, and the Hooghoudt equation to determine optimal drain spacing.
soil,water & plant relationships
The document discusses soil-water-plant relationships, including:
1) The soil-plant-atmosphere continuum (SPAC) which defines the movement of water from soil through plants to the atmosphere.
2) Soil water holding capacity is determined by soil texture, porosity, and the forces that hold water in place.
3) Effective irrigation requires understanding concepts like evapotranspiration, effective rainfall, irrigation requirements, and management-allowed deficit which indicates how much available soil water can be depleted before irrigating.
WR, NIR, GIR, ER, methods for estimating ER, Irrigation efficiencies.ppt
Water requirement of crops refers to the amount of water needed for successful crop growth over a given period. It is met through rainfall, irrigation, soil water, and groundwater. Determining the water requirement is essential for crop planning, irrigation project design, and water resource management. Methods to calculate water requirement include the water balance method, field experiments, and climatological methods. Effective rainfall refers to the portion of precipitation available for crop use, while the rest is lost through runoff and deep percolation.

Lec 9 Border irrigation – Design and hydraulics.ppt
Border irrigation involves dividing land into long, parallel strips called borders separated by low ridges. Water is introduced at the top of each border strip and flows downhill in a shallow sheet confined by the ridges. As the water infiltrates into the soil, it moves down the strip. Proper design of border irrigation considers factors like strip width and length, soil type, irrigation stream size, and slope. Check basin irrigation uses bunds to form basins that hold water for infiltration until the soil is saturated. The size and shape of check basins depends on soil type and crop grown.

New York State Rain Garden Manual
This document summarizes guidelines for designing and implementing rain gardens as an alternative stormwater management practice. Rain gardens are shallow depressions planted with native vegetation that filter and infiltrate stormwater runoff from small areas like rooftops and driveways. The summary provides details on the components and functions of rain gardens, their recommended applications for residential properties, benefits, feasibility considerations, and guidance on sizing rain gardens based on water quality volume calculations.
Estimation of runoff by table method
This document describes the table method for estimating runoff. It involves using tables to determine peak runoff rates based on watershed characteristics like soil type, slope, and land cover. The tables are separated based on watershed shape - square, broad and short, or long and narrow. Users first determine the watershed characteristics score from Table 1, then find the peak discharge rate in the appropriate watershed shape table by matching the score and area. Two examples are provided to demonstrate calculating runoff rates using this method.
Highway drainage
Highway drainage involves removing excess surface and subsurface water from roadways. Surface drainage uses cross slopes and drains to remove water from the pavement and shoulders into cross drains. Subsurface drainage uses drains and lowering of water tables to control moisture in the subgrade soil. Key components of surface drainage systems are the cross slope/camber, roadside drains, and cross drains that collect water and divert it into natural water courses.

Cu07821 ppt9 recapitulation
This document discusses water management goals and models for two agricultural areas covering 1000 hectares each. It aims for optimal water levels for farming and nature while preventing water issues. The Sobek model simulates a rainstorm over 96 hours, calculating water levels every 5 minutes for 1 month. Questions address water storage capacities in soil and surface water. Calibration requires precipitation data and variances in water levels. Simulations examine summer and winter conditions under different drainage scenarios and capacities. Maintaining infrastructure is important to ensure proper water discharge and storage.
Cu07821 10management and maintenance2015
Management and maintenance of water systems involves complying with various regulations at the European, national, provincial and local levels. It requires managing surface waters, beds, embankments, structures, water levels and other components. Key instruments used include the "Legger" which establishes the situation and dimensions, the "Peilbesluit" which sets water levels, and the "Keur" which establishes regulations. Maintenance activities include dredging, mowing, reconstructing side structures and embankments, and removing new growth. Maintenance of structures involves removing dredgings and repairing structures as needed.
Cu07821 9 zoning plan2015
The document discusses zoning plans, water assessments, and ledgers related to land development and water management. A zoning plan describes allowed land and building uses, and can regulate details like building heights and distances. Changing a zoning plan's designation requires stakeholder input and can take years. A water assessment analyzes how a zoning change, like converting farmland to urban use, will impact the water system. Ledgers document requirements for waterways regarding location, form, size, and construction, and define management boundaries and protection zones. The case involves stakeholders debating a developer's proposed zoning change, with topics including impacts to the water system and potential problems.
Cu07821 8 weirs
This document discusses different types of weirs used to measure water discharge, including broad crested weirs, thin plate weirs, and Rehbock, Romijn, Cipoletti, circular, and Thomson weirs. Broad crested weirs can be long or short, and influence discharge measurements differently depending on whether water downstream affects flow. Thin plate weirs have a sharp crest and allow measuring the upstream water level where it is streamlined with atmospheric pressure under the nappe. The document also provides a link to a video about a hydrosystem and field trip in Macedonia.
Cu07821 7 culverts new
Culverts are civil engineering structures used to allow water to pass under roads or embankments. There are several types of culverts including round concrete tubes, rectangular precast concrete elements, and metal culverts. Culverts require appropriate foundations depending on the material and site conditions, including shallow foundations, foundations on improved soil, or foundations on wooden or concrete poles. Culvert endings can have various shapes like long front walls, receding wings, or return walls to connect to surrounding terrain.

It notes key components of centrifugal pumps like impellers, volutes, and casings. It also covers pump installation methods, switching levels, frequency drives, impeller types for different uses, and hydraulic concepts like duty point and head.
Cu07821 4 soil
This document discusses the hydrological cycle and soil moisture in the unsaturated zone. It describes:
1) The process of rainfall infiltration and groundwater recharge. Water is stored in the pores of the unsaturated zone below the ground surface.
2) Forces that act on soil moisture in the unsaturated zone, including adsorption, osmotic, and capillary forces. Capillary action causes smaller pores to fill with water before larger pores.
3) The soil moisture curve and Staring series, which relate soil type to water pressure and volume of water stored. Finer textured soils like clay can store more water than coarser soils like sand.
Cu07821 3 precipitation and evapotranspiration
1. The hydrological cycle diagram shows the annual water balance for an area, with 800 mm of precipitation, 350 mm of evapotranspiration, 425 mm of surface runoff, and 475 mm of groundwater recharge.
2. Effective precipitation is defined as the volume of precipitation available for groundwater recharge, and is calculated as total precipitation minus actual evapotranspiration, which depends on crop type.
3. Extreme precipitation events like the 1998 "Westlandbui" storm that dropped 100 mm of rain in 24 hours can cause hundreds of millions of euros in flood damage.
Cu07821 2 help
This document discusses water management strategies in the Netherlands, specifically focusing on optimal water level agreements. It describes how water levels are managed through water level agreement areas, where the surface water level is fixed and uniform. The typical Dutch strategy involves examining the existing water situation and specifying adjustments to achieve an optimal groundwater and surface water regime. It also discusses how to relate crop selection and production to soil type and groundwater classification using HELP tables. Maintaining appropriate water levels is important for preventing flooding, drying out, and salination while supporting agriculture and nature.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UP
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.
