A drainage basin is an area of land where surface water converges to a single point, usually the exit of the basin. There are several types of drainage systems that form depending on the terrain and geology, including dendritic, parallel, rectangular, trellis, radial, and annular systems. Stream ordering schemes classify streams in a hierarchy based on how they join together. Quantitative analysis of drainage basins uses metrics like bifurcation ratio, length ratio, and drainage density to characterize aspects of the basin.
Drainage pattern & morphometric analyses of drainage basinsUjjavalPatel16
Drainage Pattern & Morphometric analyses of drainage basins.
In geomorphology, the patterns formed by the streams, rivers, and lakes in a particular drainage basin. Also known as drainage systems or river systems.
According to the configuration of the channels, drainage systems can fall into one of several categories known as drainage patterns. Drainage patterns depend on the topography & geology of the land.
Drainage basins: The total land surface drained by a system of stream leading to the same outflow.
Drainage system: The stream, tributaries, and other bodies of water by which a region is called drained.
Drainage divide: The boundary between adjacent drainage basins.
An area of land drained by a river and its tributaries.
It is also called the Catchment area.
Any precipitation which falls into the basin is collected and drains into the main river or its tributaries by runoff, throughflow or groundwater flow.
Its boundary marked by a ridge of high land called watershed.
Drainage basins have one main stream and many tributaries.
Each tributaries of main stream forms sub-drainage basin.

Creating a Hydrological Network for the Yukon TerritorySafe Software
The Fisheries Information Summary System (FISS) is a Federal and Provincial geo-database that provides summary level, fish and fish habitat information for waterbodies throughout the province of British Columbia. Information is georeferenced using online digitizing tools and is linked to the BC 1:50,000 watershed atlas using a hierarchical watershed coding system. Using FME, a similar watershed atlas was created for the entire Yukon Territory at a fraction of the cost and time using the Horton Order transformer and other tools. The resulting intelligent hydrolgical network is now available for the Yukon through the Community Mapping Network at www.cmnbc.ca. We will describe some of the challenges encountered in the creation of the hydrological network and provide and overview of the new Yukon FISS system.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202
A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

2. Definition:
A drainage basin is an extent or an area of land where surface water from
rain and melting snow or ice converges to a single point, usually the exit of the
basin.
Types of Drainage Basins:
(i) Dendritic drainage system
(ii) Parallel drainage system
(iii) Rectangular drainage system
(iv) Trellis drainage system
(v) Radial drainage system
(vi) Annular drainage system
(vii) Deranged drainage pattern
4. Types of Drainage Basins:
(i) Dendritic drainage system
Dendritic drainage systems (from Greek dendrites, "of or pertaining to a tree")
are the most common form of drainage system. In a dendritic system, there are
many contributing streams (analogous to the twigs of a tree), which are then
joined together into the tributaries of the main river (the branches and the trunk of
the tree, respectively). They develop where the river channel follows the slope of
the terrain. Dendritic systems form in V-shaped valleys; as a result, the rock types
must be impervious and non-porous
(ii) Parallel drainage system
A parallel drainage system is a pattern of rivers caused by steep slopes with some
relief. Because of the steep slopes, the streams are swift and straight, with very
few tributaries, and all flow in the same direction. This system forms on
uniformly sloping surfaces, for example, rivers flowing southeast from the
Aberdare Mountains in Kenya.
5. Types of Drainage Basins:
(iii) Rectangular drainage system
Rectangular drainage develops on rocks that are of approximately uniform
resistance to erosion, but which have two directions of jointing at approximately
right angles. The joints are usually less resistant to erosion than the bulk rock so
erosion tends to preferentially open the joints and streams eventually develop
along the joints. The result is a stream system in which streams consist mainly of
straight line segments with right angle bends and tributaries join larger streams at
right angles.
(iv) Trellis drainage system
The geometry of a trellis drainage system is similar to that of a common garden
trellis used to grow vines. As the river flows along a strike valley, smaller
tributaries feed into it from the steep slopes on the sides of mountains. These
tributaries enter the main river at approximately 90 degree angles, causing a
trellis-like appearance of the drainage system. Trellis drainage is characteristic of
folded mountains, such as the Appalachian Mountains in North America.
6. Types of Drainage Basins:
(v) Radial drainage system
In a radial drainage system the streams radiate outwards from a central high point.
Volcanos usually display excellent radial drainage. Other geological features on
which radial drainage commonly develops are domes and laccoliths. On these
features the drainage may exhibit a combination of radial and annular patterns.
vi) Annular drainage pattern
In an annular drainage pattern streams follow a roughly circular or concentric
path along a belt of weak rock, resembling in plan a ringlike pattern. It is best
displayed by streams draining a maturely dissected structural dome or basin
where erosion has exposed rimming sedimentary strata of greatly varying degrees
of hardness, as in the Red Valley, which nearly encircles the domal structure of
the Black Hills of South Dakota.
7. Types of Drainage Basins:
(vii) Deranged drainage system
A deranged drainage system is a drainage system in drainage basins where there
is no coherent pattern to the rivers and lakes. It happens in areas where there has
been much geological disruption. The classic example is the Canadian Shield.
During the last ice age, the topsoil was scraped off, leaving mostly bare rock. The
melting of the glaciers left land with many irregularities of elevation, and a great
deal of water to collect in the low points, explaining the large number of lakes
which are found in Canada. The watersheds are young and are still sorting
themselves out. Eventually the system will stabilize
Stream Ordering System:
Stream ordering refers to the determination of the hierarchical position of a
stream within a drainage basin.
(i) Gravelius Scheme of Stream Ordering
(ii) Horton’s Scheme of Stream Ordering
(iii) Strahler’s Scheme of Stream Ordering
(iv) Shreve’s Stream-Link Ordering Method
10. Quantitative Analysis of Drainage Basins:
